Answer:

2HCl → H2 + Cl2 = decomposition

NaF + KBr → NaBr + KF = double replacement

Mg + MnCl2 → Mn + MgCl2 = single replacement

2Na + 02 → Na2O2 = combination

Explanation:

A chemical reaction involves the conversion of one or more substances called REACTANTS into other substances called PRODUCTS. There are different types of reactions depending on how it occurs, they include:

- Combination or synthesis reaction is a type of reaction in which two or more elements combine to form a single product. Example is:

2Na + 02 → Na2O2

- Single replacement is a type of reaction where one element is replaced by another in a compound or molecule. Example below shows that Manganese (Mn) is replaced by magnesium (Mg):

Mg + MnCl2 → Mn + MgCl2

- Double replacement is a type of reaction where two elements are replaced by other elements at a time. Example is:

NaF + KBr → NaBr + KF

- Decomposition is a type of reaction in which one molecule or compound is broken down into two or more products. Example is:

2HCl → H2 + Cl2
